SPECIFICATION forming part of Letters Patent No. 775,169, dated November 15, 1904.

Application filed July 29, 1903. Serial No. 167,472. (No model.)

To all whom/ it natty concern:

Be it known that 1, ROBERT BURNS G001)- YEAR, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Shuttle- Box-Actuating Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in mechanism for actuating shuttleboxes for pick-and-pick shuttle-motions for looms.

It has for its object to simplify the construction and arrangement of the parts and otherwise improve the same; and the nature thereof consists of the combination of said parts, substantially as hereinafter more fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, illustrating arranged in horizontal alinement with each other. In the upper slots 3 is fitted a sliding transverse impelling-bar A, and in the lower slots 3 is similarly arranged a like impellingbar 4:, these bars being actuated to move simultaneously in opposite directions. A transverse rock-shaft 5 is journaled in suitable bearings in said side or lateral portions 2, t the ends of which shaft are secured levers 6 6, one of which levers has two arms 6" 6 the opposite lever 6" having three arms 6 6 6, the purpose of which will presently appear. The arm 6 of the lever 6 and the arm 6 of the lever 6 are connected by pitmen 7 7 to the ends of the sliding or impelling bar I, and the arm 6 of the lever 6 and the arm 6 of the lever 6 are likewise connected by pitmen 8 8 to the ends of the second sliding or impelling bar A. AS said rock-shaft is actuated to throw the arms 6" 6 in one direction and the arms 6 6 in the reverse direction said pitmen move the two sliding or impelling bars in reverse direction simultaneously,

the preferred embodiment of my invention, said bars being guided within their respective 7 25 Figure 1 is a side elevation. Fig. 2 is an opslots to move horizontally in planes one above posite side elevation. Fig. 3 is a plan View. the other. The arm 6 of the lever 6 projects Fig. A is a longitudinal section taken on the centrally from said lever at right angles to the line in a of Fig. 3, and Fig. is a transverse arms 6 6, and to one end of said arm (S is section taken on the line y 2 of Fig. 4. Fig. pivoted the upper end of a link 9, the lower 75 3 6 is a detail view of one of the links and end of which link is connected or pivoted cams 14. to a cam 10, said cam being carried by a ro- It will be understood that I do not limit mytary shaft 11, suitably journaled in the loomself as to details as herein disclosed, as the frame and driven in any suitable manner. same may be changed as circumstances sug- At each side of the heddle-harness are argest without departing from the spirit of my ranged certain parts comprising a draw or invention and the same remain intact and be latch bar 12, with one end guided in an aperprotected. tured end bar of the frame 2, said latch or In carrying out my invention I employ the draw bar having near one end a longitudinal usual framework 1 for supporting the opera slot 12, adapted to receive a cross-rod 13, se- 5 4 tive parts of the shuttle mechanism and the cured in the lateral pieces of said frame 2. other parts of the loom. Suitably supported Pivoted or connected up with said latch or in position in said frame at each side is a supdraw bar are slides or cams 14, each having plemental frame 2, comprising lateral portwo inclined slots 14 14:", one of said slots retions 2, having produced in each of said latceiving a cross-rod 1A, also secured in the 90 eral portions parallel longitudinal slots 3 3,

the upper and lower ones of said slots being lateral portions of the frame 2, the slot 14.- of said slides or cams having opposite inclinations, the object of which will presently appear. A lever 15 has one end pivoted upon the cross-rod 14: and has projecting from opposite sides thereof a cross-pin 15*, fixed to -said lever 15, with one end engaging the slot 14c of the slide 14% and its opposite end having connected thereto a pitman or rod 16, connected to a second lever 17 at one end, in turn suitably connected to the shuttle-box-actuating rod 18. Said lever 17 has connected thereto, as at 17*, a second pitman or rod 17*, connected at its upper end to similar parts as said first-named pitman. Intermediately of the points of connection of said pitmen with said lever 17 said lever is provided with an elongated vertical slot 17, receivinga stud or projection 17 from the loom-frame, thus permitting said lever to have a sliding vertical movement upon said projection as said lever is actuated by said pitmen. It will be observed that by the downward stroke of the pitman 16 the pitman or rod 17 X will be raised and the shuttlebox-actuating rod will be lifted, so as to dispose one of its shuttles for removal therefrom upon the race, while upon the downward stroke of said pitman 16 the operation will be reversed. It is obvious that the inclination of the slots 14 of the slides 1 L will govern the length of the strokes of the pitmen 16 and 17 and that the inclination of the slot 14: of one slide 14 upward should correspond to that of the slot 14: of the other slide 1a downward. Connected to a shoulder or elevation 12 of said latch-bar 12 is a jack 21, arranged to have endwise movement and supported intermediately of the impellingbars & 4, with its free end resting upon a finger 2'1, pivoted at one end in the frame 2* directly above the pattern-cylinder 22, suitably journaled and actuated in said frame. has oppositely-facing shoulders 20 20 upon its upper and lower surfaces, respectively, adapted to be engaged by the oppositely-moving impelling-bars 4: 4. It will be observed that when the pattern-cylinder provided with suitably spaced-apart tappets or studs 22 is in operation said tappets or studs will engage the finger 21, imparting a vibratory movement thereto, which in turn will similarly actuate the jack 21, said movement being timed with the reciprocating movement of the impelling-bars 4: 4:, so as to permit said bars to engage the oppositely-facing shoulders of said jack at the required intervals as said impellingbars are themselves actuated, thus imparting a longitudinally-reciprocating movement to the draw or latch bar 12. Said draw or latch bar will accordingly actuate the slide or cam lL and transmit, through the lever 15 and its pin 15, a vertical reciprocating motion to the pitman or rod 16, and by means of similar parts, as just described, a like movement will be imparted to the pitman 17 Said movements of said pitmen alternate with each other,

Said jack" thus actuating the shuttle-box, as and for the purpose above described.

Having thus described myinvention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a device of the character described, the

combination of a shuttle-box-actuating lever,

means efi'ecting connection between said lever and the shuttle-box, mechanism having a reciprocated motion, and pitmen effecting connection between said reciprocated mechanism and said lever, said lever having intermediately of the points of connection therebetween and said pitmen an elongated slot receiving a stud or projection from a fixture.
